HydroSeal 105 1K is a single-component, polymer-modified, cement-based waterproofing slurry that incorporates advanced micro silica polymer and fibre technology. When cured, it forms a dense, high-adhesion matrix that is impermeable to water up to 10 bar on both the positive and negative pressure sides of a structure.
This versatile waterproofing solution serves five different functions in one product, making it an essential addition to any waterproofing toolkit. Whether used as a mortar, tanking slurry, surface repair material, fairing coat, or waterproof render, HydroSeal 105 1K delivers exceptional performance with quick strength gain and fast drying times.
